When I was younger I was more attracted to immortality than I am now. I think I was worried there were various things I might not live to do — travel, fatherhood, publishing. But now I'm more accepting of death. Nothing lasts. The petals whirl, the leaves fall, the river flows. Why fight it? You get the one lifetime and it's enough. At some point you have to let go. I think people who obsess about becoming immortal are on an ego trip. They don't want to accept that the world will go on just the same without them. Certainly, as technology advances, we'll see people living longer. And, at the more SF end of things, you might look for injectable nanobots to repair your body, or the use of fresh tank-grown clone bodies, or the ability to upload your mind into an artificial android body. I wrote about the last of these in my novel Software, thirty years ago. But in reality I don't see any of these things happening very soon. Recently there's been a lot of hype about the singularity. The word means different things to different people. In a way, we're already well past a singularity, which was the coming of the computers. But some people have a feeling that a really big change is coming very soon. And there's a hope that if you can just hang on for, say, another thirty years, then the nanobot or clone-body or digital-upload version of immortality will be available. Note that many of those spreading this promise are also offering to sell you expensive vitamins to help you hang on. They're selling snake oil. It's a con.
